"Both of my calves were blown out," he said. "That’s how I hurt my shoulder. I needed a complete up-and-down rehab." His longtime personal physical therapist, Chris Correnti, who worked for the Red Sox and is now in the Mets’ organization, supervised his rehab. "It was really, really intense," Martinez said of his rehab. "The most intense work I’ve ever done in my life. Two times I threw up while training and peed in my pants because I was out of control, it was so hard. I couldn’t do anything about it. "I’ll tell you this. I wouldn’t do it again."
